BOSS Audio Systems CPRD2 Car Audio Capacitor - 2 Farad, Energy Storage, Enhance Bass From Stereo, Warning Reverse Polarity Tone, Voltage Overload Low Battery, for Amplifier and Subwoofer

I was skeptical on getting this 2 farad capacitor because it was so cheap but, it actually works as good if not better than the more expensive ones! I must complain at the fact that Walmart shows a wiring kit in the pictures with the capacitor even though it doesn't come with one... Still It does great and I couldn't complain about the price.

I hooked it up like the manual said to, instead i ran 12+ for sub amp off the cap power in. My 4 channel tapped in at my junction block. Still had dimming lights as per manual. This way no more dimming lights. Went from 14.4 to sometimes 12 + per manual, this way it never drops below 13.9. I know people say that boss is junk but this one is working for me.
